A flex fan has blades that move plenty of air at low speeds, but straighten out at high speeds, resulting in less air resistance.
I am skeptical of 15 horsepower gains. I doubt the fan on a 3800 rpm engines takes that much hp. Now the fan on a full race 8,000rpm engine might suck that much power...
